Comment 5 for bug 1154065

Same here. I noted that black screen is displayed the second time lightdm runs.

After downloading, configuring, making and installing lightdm-webkit-greeter I started the service and I could see the greeter showing that couldn't load theme. That was because theme path was wrong. I fixed the path, restarted the service and I got a black screen every time. I thought it was configuration issue, I try everyting until I decided to reboot to see why I was able to get it to work just once.

After reboot, the greeter appeared. I switch to a terminal, restarted the service, and then the black screen appeared again.

I've checked the log, I googled 'lightdm failed to open CK seesion' and I landed here.

Fedora 19, x86_64, installed version lightdm-webkit-greeter-0.1.2.
